Intercooling my 91.0
 

I've got a non ic 1ton. What all parts would I need from a 91.5+ truck to make mine intercooled? Or is there an aftermarket kit I can use? What's the price difference going to be and what advantages will it bring? Thanks!

i have a 90 i intercooled, this i what i did: godspeed 4"x12"x30" intercooler off of ebay,
3" piping kit off of ebay(gotta look at the import stuff) all my couplers came from www.max-redline.com i got a 1st gen intercooled intake horn from commins power systems, i had to "shave" my grill for the ic to fit but i still have my stock grill in place. i had to flip the intake cover around so the intake horn would clear the master cylinder, and had to extend my intake heater wires. umm if i had to do it again i would have gotten piping made for the truck instead of doing it myself. we got a local guy that does that kinde of stuff the guy does amazing work. i may still get him to make me a set of pipes. ummm.......
it took me a friday night and the rest of the week end to do
oh i forgot i got my clamps from five star international
i lost 300* off of my egts and the truck seems to run a lot better
i did however lose like 7psi....din't seem to make a difference
hope this helps

That's because the charge-air entering the engine is now denser (cooler). The intercooler is doing it's job. ;)

Nice work pulling all the parts together and putting it together. Atleast when you start something you finish it. Nice work

Wow man thats a nice setup, i have a 92 thats intercooled, but i'm custom makeing my 3'' intercoolertubes i'll post picks when i get it finished

it took a little to get the piping right but the end result was worth it. think i only have about $600 into it.

thats pertty damn good actually!:tu:

yea way cheaper then getting everything off of a 1st gen intercooled, cummins prices are nuts. i paid 78+ tac for the intake horn. plus i was talken to a local guy that intercooled his 89 and he said he only lost 150* with an powerstrock intercooler. so i'd say i got the better end of the deal...however to fit that 4" thick intercooler i had to ditch the ac condensor ofr now. i gotta look at work and see if i can get a low profile mount condensor to fit above the intercooler, but i never use ac anyway so that will be a project for later.

Sweet. Thanks for the input. So there is no other tuning you have to do to get it to work right? I mean, I'm used to working on Hondas. My friend boosted his si, then switched intercoolers and had to retune. But that car is also pgm-fi too. All electronic

No extra tuning needed!

Well... With your new lower temps you COULD add some more fuel and get some more power, but you dont have too... :D

i just about finished off the pump, can still go about a turn and a half, gonna wait to do that when i get a new turbo.
